Subdirectory property in git links

Poetry does not allow for installing dependencies from a VCS repository which has .toml/setup.py file not in root directory. As an example you can do that in pip by using this command: https://stackoverflow.com/a/19516714

Subdirectory property is not used when installing dependencies from a git repository. It looks like property can be extracted from git link:
https://github.com/sdispater/poetry/blob/master/poetry/packages/utils/link.py#L127
but is not taken into account after checking out a git repository. (directory is not changed to specified subdirectory). Directory switch should happen here: https://github.com/sdispater/poetry/blob/master/poetry/puzzle/provider.py#L177
